STATUS BYTE Description
00h
GOOD
The command has been successfully completed.
02h
CHECK CONDITION
An error, exception, or abnormal condition has been detected. The sense data is set by the
drive. The REQUEST SENSE command should be issued to determine the nature of the
condition.
04h
CONDITION MET
This status is returned when an unlinked PRE-FETCH command has been successfully
completed.
08h
BUSY
This condition is returned when disconnect privilege is not granted while the drive is BUSY
processing the other command for the other initiator. The normal initiator recovery action is to
issue the command at a later time or to reissue the command and grant the disconnect
privilege.
10h
INTERMEDIATE
Not supported.
14h
INTERMEDIATE CONDITION MET
Not supported.
18h
RESERVATION CONFLICT
This status is returned whenever an SCSI device attempts to access the drive, but it has been
reserved by another initiator.
28h
QUEUE FULL
This status indicates that the target's command queue is full. If a tagged command queuing
feature is enabled and there is no room on the command queue, this status is returned when the
initiator sends a command. For this status, sense data are not valid.
